Answer:
30 m^2.
Step-by-step explanation:
This is a right-angled triangle because it obeys the Pythagoras theorem
( 13^2 = 12^2 + 5^2).
So its area = 1/2 * base * height
= 1/2 * 5 * 12
= 30 m^2
Answer:
x = 7
Step-by-step explanation:
12x - 16 = 68
Add 16 to each side
12x - 16+16 = 68+16
12x =84
Divide by 12
12x/12 = 84/12
x = 7
Answer:
The equation is;
y = (-x-23)/25
Step-by-step explanation:
The equation of a straight line can be given as y = mx + b
where m is the slope and b is the y-intercept
for y = 25x + 4
m is 25
Now, we need the slope of a line perpendicular to this,
If two lines are perpendicular, the result of the product of their slopes is -1
m1 * m2 = -1
25 * m2 = -1
m2 = -1/25
Mathematically, we have the slope in the point slope form as ;
y+3 = -1/25 (x - 2)
y = -x/25 + 2/25
y = -x/25 + 2/25 - 3
y = -x/25 -73/25
Answer:
D
Step-by-step explanation:
usually anything with 11 on the numerator is a repeating decimal and the 0.37 is closest to 36.
so by guessing you know is D
